Presumably the proper motion of about o"o3 is in A. This 
will appear from later measures of C.

The brightness of B 
seems to have been greatly over-esti- 
mated in 1901. I have 
connected with 
it a faint star. These 
are all the measures of BC. 
We have for the proper motion of A

From the five positions by 2 , A, HI and (3 (1829-1909), the 
proper motion of A is: 
o"o44 in 8 i?5 
Although it is practically certain that B is fixed, I have 
measured a third star.

As he calls it very difficult, and the distances differ L'4, 
there is probably no change.
